What you have done is obv fine and improves what we had, still not seen a single Hawk with an issue closing the doors over here, but yours can work against any operation airspeed :-)
Today another Hawk kit arrived from CARF, my unit now has four 2010 schemed Hawks in it, one SG and three 1:5.5, the EDF and now two for turbine P-140RX...need to talk the next guy out of this scheme :-)) Least the SG kit leaving Germany today is white...unfortunately I think the owner is going to have it painted...in 2010 scheme too!
